/: Change Scan Response Data (SRP) dynamicallyHow to change the SRP data is a very imperative for most bluetooth low energy use case. but in official Texas Instruments (TI) example code, there is no demonstration for this purpose. in here, I note how to reach the goal.In the TI forum, it sai possible to update RSP data by disabling/enabling advertising. but for my feeble trying, the RSP do not be updated. s

The idea of SRP was first proposed by Tom DeMarco and is an important component of cohesion.

Single principle of responsibilitySRP (the single Responsibility Principle): A class should have only one reason for the change. The change here refers to the change of duty.The SRP is well understood, and its requirement is to have a class do only one type of responsibility, and this class needs to be decomposed when the class takes on other types of responsibility . It sounds simple, that is, a class means doing a thing. Here is not one thing.If a c

8) the PAM Authentication Module provides authentication information to applications through the PAM library.9) after the authentication is completed, the application has two options:Grant the required permissions to the user and notify the user.The authentication fails and the user is notified.The PAM workflow is shown in Figure 1.

the Phonestoresale class above, can cause it to change that only sale responsibility changes, this class changed. Do not allow a class to be multi-professional, which creates a great degree of coupling.Advantages: 1. Improve the readability of the class, easy to maintain; 2. The complexity of classes is reduced, and a class is responsible for only one responsibility; 3. The risk of change is reduced, the change is essential, but it is a class is a responsibility, modifying a class is equivalent
Single Responsibility Principle (SRP): For a class, there should be only one reason for its change. If a class has too many responsibilities, it is equivalent to coupling these responsibilities. A change in responsibilities may weaken or suppress the class's ability to fulfill other responsibilities. When a change occurs, the design will be unexpectedly damaged. Much of software design really needs to do is to discover accusations and separate those r
SRP (single responsibility principle, single responsibility principle)
A class should have only one reason to change.
One class is better to do only one thing. There is only one reason for its change.A class has only one reason for its change. Otherwise, reconstruction should be considered.A single responsibility principle is determined by the reasons for changes, rather than functional responsibilities. Although a job is often the axis of change,
